Linux Compton 配置高级技巧

Compton 是一个轻量级的X11合成管理器，常用于提升Linux桌面环境的视觉效果和性能。以下是一些高级配置技巧，可以帮助您优化Compton的使用体验。

1. 性能优化配置

# 启用后端检测
backend = "glx";

# 使用更快的阴影算法
shadow-radius = 7;
shadow-offset-x = -7;
shadow-offset-y = -7;
shadow-exclude = [
    "name = 'Notification'",
    "class_g = 'Conky'",
    "class_g ?= 'Notify-osd'",
    "class_g = 'Cairo-clock'",
    "_GTK_FRAME_EXTENTS@:c"
];

# 减少重绘区域
xrender-sync-fence = true;

2. 透明度和模糊效果

# 窗口透明度设置
opacity-rule = [
    "90:class_g = 'Terminal'",
    "85:class_g = 'Code'",
    "100:class_g = 'Firefox'"
];

# 启用模糊效果 (需要编译时启用kawase模糊支持)
blur-background = true;
blur-method = "kawase";
blur-strength = 5;
blur-background-exclude = [
    "window_type = 'dock'",
    "window_type = 'desktop'"
];

3. 动画和过渡效果

# 窗口动画设置
animations = true;
animation-for-open-window = "zoom";
animation-for-transient-window = "slide-down";
animation-for-workspace-switch-in = "slide-up";
animation-for-workspace-switch-out = "slide-down";

# 动画参数
animation-stiffness = 300.0;
animation-window-mass = 0.5;
animation-dampening = 25.0;

4. 多显示器配置

# 针对不同显示器设置不同参数
glx-swap-method = "buffer-age";  # 减少延迟
glx-no-stencil = true;  # 提高性能

# 针对特定显示器关闭合成
unredir-if-possible = true;
unredir-if-possible-exclude = [
    "class_g = 'Firefox'"
];

5. 高级排除规则

# 更精细的窗口排除控制
fade-exclude = [
    "class_g = 'slop'",  # 区域选择工具
    "class_g = 'rofi'"   # 启动器
];

# 不绘制特定窗口的阴影
no-dnd-shadow = true;
no-dock-shadow = true;

6. 调试和故障排除

# 启用日志记录
log-level = "info";
log-file = "/tmp/compton.log";

# 性能分析标记
paint-on-overlay = true;
glx-no-rebind-pixmap = true;

7. 与特定WM/DE集成

# 针对i3wm的优化
mark-wmwin-focused = true;
mark-ovredir-focused = true;
use-ewmh-active-win = true;

# 针对KDE的优化
detect-rounded-corners = true;
detect-client-opacity = true;

8. 高级GLX设置

# 高级GLX选项
glx-copy-from-front = false;
glx-use-copysubbuffermesa = true;
glx-no-rebind-pixmap = true;
glx-swap-method = "exchange";  # 或 "buffer-age"

最佳实践建议

1. 逐步测试：每次修改少量配置并测试效果，避免同时修改多个参数
2. 性能监控：使用glxinfo和glxgears测试图形性能
3. 配置文件管理：将配置放在~/.config/compton.conf或~/.compton.conf
4. 版本适配：不同版本的Compton可能支持不同特性，检查您的版本支持哪些功能

通过合理配置这些高级选项，您可以显著提升Linux桌面的视觉体验和性能表现。
